6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Greg Kroah-Hartman gregkh@linuxfoundation.org
This reverts commit 983e6b2636f0099dbac1874c9e885bbe1cf2df05 which is commit 8a2f11878771da65b8ac135c73b47dae13afbd62 upstream.
It wasn't needed and caused a build break on s390, so just revert it entirely.
